Sphinx warnings

[VincentRouvreau]

When generating the python doc, I have these warnings:

build/python/gudhi/cover_complex.py:docstring of sklearn.utils._metadata_requests._MetadataRequester.get_metadata_routing:3: WARNING: undefined label: 'metadata_routing'
build/python/gudhi/cover_complex.py:docstring of sklearn.utils._metadata_requests.RequestMethod.__get__.<locals>.func:3: WARNING: undefined label: 'metadata_routing'

In sphinx documentation, they are talking about misspelled references.
I tried set(SPHINX_PATH "${PYTHON_EXECUTABLE}" "-m" "sphinx.cmd.build" "-vvv") but could not find those.
